Size
Tungsten carbide burrs come in a variety of sizes to suit different
applications. Choosing the right size will depend on the job at
hand. Generally smaller burrs are used on smaller applications for
producing finer, smoother work. Larger burrs are for higher, faster
stock removal and are more often used on larger jobs.
Size No. | Burr size | RPM |
No.42 | 2.4mm | 17,000-26,000 |
No.43 | 3.0mm | 17,000-26,000 |
No.1 | 6.0mm | 11,000-16,500 |
No.5 | 13.0mm | 8,000-12,000 |
No.6 | 16mm | 7,650-11,500 |
Speed
The rotary tool speed you use will depend on the metal and
size/type of burr used. For optimum performance and results it is
always best to check the manufacturer recommendations for the
correct RPM to use with each metal burr. Ideally you will start off
at a lower speed and increase as you go along, however if you find
your burr is chipping it is a sign you are going too slow. Here is
a general rotary tool speed guide
Technique
For the best results, and to make your burr last longer, make sure
you don't use too much pressure while cutting. Too much pressure
will cause the cutting edges of the flutes to chip and become
smooth prematurely, reducing the life of your burr .
You will also want to ensure you keep the burr moving around the
cutting area as much as possible. If the metal burr is left still
for too long this can cause clogging and stop it from digging and
jabbing into the job, leaving a rough job with visible marks.
Company Profile
Joint carbide co.,ltd was established on January 21, 2019, as a sales branch established
by Zigong joint carbide co.,ltd in Chengdu.Our company covers
20,000 square meters was a high-tech enterprise integrating
research, development, production and sales of cemented carbide
products and cemented carbide rotary burrs,carbide tire
studs,carbide repair tire stud,carbide particles & composite
welding rods.

The company is committed to providing high-precision, high-speed
and efficient metal grinding solutions and services for the
machinery manufacturing industry. The company introduced the most
advanced international five-axis five-linkage CNC tool grinder,
three-coordinate tool detector and other equipment from Germany.
The aim is to produce high-quality, internationally competitive
products using internationally advanced equipment. At present, our
company has become the largest rotary file production base in the
country, with a mature R&D team and management team in China,
and a stable supply chain.

As a metal cutting tool, the rotary file has been exported to
Europe, North America, South America and a small number of
Southeast Asian countries.A few days ago, the company has completed
the accumulation of various infrastructure and technology research
and development. Since 2020, our company has added 200 five-axis
and five-linkage rotary grinders. By 2023, our company will invest
a total of 400 five-axis and five-linkage rotary grinders. Grinding
machine (total value 150 million yuan). By then, our company will
become the world's largest supply base for rotary files.We have the
world's advanced raw material cemented carbide formula technology,
the most optimized advanced manufacturing process, and the
largest-scale production equipment.
